The carotid arteries are present on each side of the neck. To detect the presence of a narrowing of these arteries or obstruction, a carotid ultrasound (duplex) may be performed. A transducer is placed on each side of the neck. Harmless sound waves leave the transducer and bounce off the carotid arteries and return to the transducer. These sound waves are converted to images that may be recorded. A Doppler will also be obtained by bouncing sound waves off the carotid vessels to obtain blood flow patterns. There is no preparation for this test. One hour should be allowed for this test. A physician will read the test.
